How to Implement Pre‑warming in the Spring Ecosystem: Extension Points and Their Execution Order

Implementing pre‑warming in Spring involves using several extension points—SmartLifecycle, ApplicationListener for ContextRefreshedEvent, InitializingBean, @PostConstruct, ApplicationRunner, and CommandLineRunner—each with specific execution timing and ordering considerations to ensure cache loading occurs before the web server starts handling traffic.

Graceful Shutdown Support in Spring Boot 2.3+ for Embedded Web Servers

Since Spring Boot 2.3.0.RELEASE, graceful shutdown is supported for all embedded web servers (Jetty, Reactor Netty, Tomcat, Undertow) and both reactive and servlet‑based applications, using SmartLifecycle beans, configurable timeouts, and a JVM shutdown hook to allow in‑flight requests to finish while refusing new ones.

Graceful Shutdown of RocketMQ Consumer in Spring Applications

The article recounts a production incident caused by an ungraceful RocketMQ consumer shutdown, analyzes the root cause involving Spring's bean destruction order and ShutdownHook behavior, and presents two solutions—using the official Spring‑Boot starter with SmartLifecycle or handling ContextClosedEvent—to achieve orderly termination.
